针对传统油井测量仪器体积大、价格贵等问题,设计了一种新型高效的智能三臂测井仪器.该测井仪器将传统的仪器做成以SPCE061A单片机为核心的嵌入式系统,其集成度高,大部分功能用软件实现,包括测量、计算、结果校正、显示、仪器量程自动校正和存储、语音提示、报警等模块.实验证明,该系统能够稳定工作,可靠性高,测量精度可达2%,能够满足实际油井直径测试要求.%To solve the problems of large volume and high cost of traditional oil well measuring instruments,a new-type in-telligent three-arm logging instrument with high efficiency was designed. Instead of the traditional instruments,the embedded system with high integration density based on SPCE061A was implemented,whose most of functions can be realized with soft-ware,including measurement,calculation,result calibration,display,automatic correction/storage of instrument range,voice prompt and alarm modules. The experiment results show that the system has better stability and reliability,and its measuring ac-curacy can reach 2%,so it can meet the requirements of actual test of oil well diameter.
